Haldatec have available controllers and timers that are used with sampling, odourant injection, flow, pressure and temperature recording. All can be used in stand-alone situations.

Controllers

Signal to pulse converters and timers easily convert a digital or analogue signal to a pulse output to drive solenoid valves for use with sampling and chemical or odourant injection.

Pneumatic timers for driving pneumatic actuators on samplers or other devices.

Typical uses would be ship loading and off loading and stand alone installations such as pipeline installations where electrical power is either not available or poses complications for hazardous area installations.
